如何用程序做地理性能测试

Question

我想测试我的程序在有和没有索引的情况下的性能，并比较经过的时间和 cpu 时间。我的程序如下所示：

create procedure p_search_vehicle
    @IdCustomer int,
    @idGroupVehicle int = null,
    @ResultCount int= null,
    @Radiant int= null 
as
begin
    if @IdCustomer is null
    begin
        print 'The argument cannot be null'
        return 
    end

    declare @start geography

    set @start = (select location from Customer where idCustomer = @idCustomer)

    --- @Result null group null radiant null
    if @ResultCount is null and @idGroupVehicle is null and @Radiant is null
        select top 10 
            idVehicle, idGroupVehicle, brand, model, maxRange, weight, maxSpeed, nameLocation, @start.STDistance(locationVehicle)/1000 as distanceInKm
        from 
            Vehicle 
        where 
            (@start.STDistance(locationVehicle)/1000 is not null)
        order by 
            @start.STDistance(locationVehicle)/1000 asc
    ---@Result null  radiant null
    else if @ResultCount is null and @Radiant is null
        select top 10 
            idVehicle, idGroupVehicle, brand, model, maxRange, weight, maxSpeed, nameLocation, @start.STDistance(locationVehicle)/1000 as distanceInKm
        from 
            Vehicle 
        where  
            idGroupVehicle = @idGroupVehicle 
            and (@start.STDistance(locationVehicle)/1000  is not null)
        order by 
            @start.STDistance(locationVehicle)/1000 asc
    ---@Result null  
    else if @Radiant is null
        select top(@ResultCount) idVehicle,idGroupVehicle,brand,model,maxRange,weight,maxSpeed, nameLocation , @start.STDistance(locationVehicle)/1000 as distanceInKm
        from Vehicle 
            where idGroupVehicle= @idGroupVehicle  and  (@start.STDistance(locationVehicle)/1000  is not null)
            order by @start.STDistance(locationVehicle)/1000 asc
             ---@@idGroupVehicle  null @Radiant is null
            else if  @idGroupVehicle is null and @Radiant is null
    select TOP(@ResultCount) idVehicle,idGroupVehicle,brand,model,maxRange,weight,maxSpeed, nameLocation , @start.STDistance(locationVehicle)/1000 as distanceInKm
        from Vehicle 
            where  (@start.STDistance(locationVehicle)/1000  is not null)
            order by @start.STDistance(locationVehicle)/1000 asc
            ---@idGroupVehicle is null and @ResultCount is null
            else if  @idGroupVehicle is null and @ResultCount is null
    select top 10 idVehicle,idGroupVehicle,brand,model,maxRange,weight,maxSpeed, nameLocation , @start.STDistance(locationVehicle)/1000 as distanceInKm
        from Vehicle 
            where  (@start.STDistance(locationVehicle)/1000   <= @Radiant)
            order by @start.STDistance(locationVehicle)/1000 asc
        --- @idGroupVehicle is null 
            else if  @idGroupVehicle is null 
    select TOP(@ResultCount) idVehicle,idGroupVehicle,brand,model,maxRange,weight,maxSpeed, nameLocation , @start.STDistance(locationVehicle)/1000 as distanceInKm
        from Vehicle 
            where  (@start.STDistance(locationVehicle)/1000   <= @Radiant)
            order by @start.STDistance(locationVehicle)/1000 asc
            --- all options
    else
    select TOP(@ResultCount) idVehicle,idGroupVehicle,brand,model,maxRange,weight,maxSpeed, nameLocation , @start.STDistance(locationVehicle)/1000 as distanceInKm
        from Vehicle 
            where idGroupVehicle= @idGroupVehicle  and  (@start.STDistance(locationVehicle)/1000  <= @Radiant)
            order by @start.STDistance(locationVehicle)/1000 asc
 end
 go

我已经使用 SET STATISTICS IO, TIME ON 测试了这个过程 DBCC FREEPROCCACHE； DBCC DROPCLEANBUFFERS；检查点去吧，但我必须改变一些东西才能进行测试，永久设置所有参数并丢弃创建过程并声明每个参数

SET STATISTICS IO, TIME ON 
DBCC FREEPROCCACHE; 
DBCC DROPCLEANBUFFERS; 
CHECKPOINT

是否可以通过其他方式测试过程以显示执行时间和受影响的行，而不对过程进行任何更改？

Answer 1

您不必将您的程序转换为测试脚本。而只是调用它。并且不要使用冷过程或页面缓存进行测试。这是一个非常不寻常的状态。

SET STATISTICS IO, TIME ON 
GO

declare @IdCustomer int = 1,
 @idGroupVehicle int = null,
 @ResultCount int= null,
 @Radiant int= null 

exec p_search_vehicle @IdCustomer, @idGroupVehicle, @ResultCount, @Radiant
GO
SET STATISTICS IO, TIME OFF
